DataAnalysis 2.0.18
Device: iOS iPad Only
Category: Productivity
Price: Free, Version: 1.23 -> 2.0.18 (iTunes)
Description:DataAnalysis is a general purpose iPad App for the plotting and analysis of all types of data that can be formulated as x,y pairs. The program can be used easily by both students and professionals. It is particularly useful for quick analysis of various types of data by curve fitting, analysis of data via a standard curve, and analysis of various types of kinetic data including enzyme kinetics.
Data can be entered directly via the keyboard or imported from the Mail App as a text file (.txt), a comma separated value file (.csv) and a gzipped csv file (.csv.gz). In addition, data can be imported via drag and drop within iTunes. Data files in txt, csv, csv.gz and native formats can be imported directly from DropBox.
After data entry the user has the option to average, baseline correct, and/or normalize the data before plotting and fitting.
Plotting of the data is as simple as pressing the Plot button. The axes are autoscaled and the graph is immediately ready to add to a document or presentation. The user has a variety of options to customize the graph by altering the axes, axes labels, graph title, and changing the symbol, its size and color.
The data can be fit to a variety of math equations by non-linear regression including simple functions such as linear, 2nd and 3th degree polynomials, power, exponential, and log functions. Data can also be fit to more complex equations for such processes as radioactive decay, enzyme kinetics, 1st and 2nd order chemical reactions, etc. The fit can be overlaid on the data with different line widths, types and thicknesses.
For many analytical situations, the data fit can be used as a standard curve to determine the value of unknowns. This analytical procedure is completely automated within DataAnalysis.
The program output, graphics and text, can be emailed, or uploaded to Dropbox in a variety of formats including PDF, PNG and TXT. The graphics in PDF format can be edited with programs like Adobe Illustrator™ as objects.
DataAnalysis also supports multitasking and printing of input data as well as all forms of output.
DataAnalysis has instructions and how-to videos available via the Help Menu.
What's New
This is the first major upgrade of DataAnalysis. This version is also completely redesigned to take advantage of the new features in iOS 7 (if available). DataAnalysis remains compatible with all iPads with iOS 5.1.1 and above.
New Feature List:
64 bit support on iPads with the A7 processor. Data fitting on large data tests is improved because the Apple LLVM compiler has been optimized to take full advantage of the 64 bit A7 processor.
Tool tips are available from the HELP menu item on each page. In addition, a direct link to the extensive HELP system on the DataAnalysis website is provided via a button on each page that is accessed from Tool tips.
Files can now be deleted directly from the startup page. Simply press the EDIT button, select one or more files to be deleted then press the Trash can. If you decide not to delete the files simply press the DONE button. Tool tips are also available on the EDIT page.
DataAnalysis can now handle hundreds of files with each having up to 2000 points. A sample data file is now included with a 2000 point data set.
Additional keys are available on the keyboard to make data entry easier, including cursor left and right, tab and enter exponent.
Manual scaling of the axis is now available. Simply double tap near the xmin, xmax or ymax
values and type in the new value followed by return
The graph title, x and y axis labels and data points are now saved. Input of axis labels and the graph title is via the Graph Options Popover from the Graphics View.
Improved Dropbox support.
